Be sure you are not also running KVM, VMware, or any other VM
software. At this writing, only one virtualization platform can run at
a time.
LXC is not a virtualization platform (because it doesn't run
multiple kernels on one CPU). So your VirtualBox freeze-ups are
probably not related to the use of LXC (but I haven't tried it myself).

Here are some of the cases that I have tried:
1.) Starting a VirtualBox VM when an LXC container is already
running effectively freezes the host.
2.) Starting an LXC container when a VirtualBox VM is already
booted is fine.
3.) Starting another LXC container after point (2) is also fine.
4.) Starting antother VirtualBox VM after point (3) is also fine.
Could somebody kindly share some light here? It seems that the
initial startup of the VirtualBox module is the trigger here. Does
LXC and VirtualBox really could co-exists together at the same time?
Yes. They have no problem working together for me.
I intend to utilize the VirtualBox VMs for
other-than-Linux-workload, whereas the LXC containers for all
Linux workload. For the info, the host is a Linux Mint 13
(3.2.0-33-generic 64-bit) using VirtualBox 4.2.4. Both VirtualBox
VM's files and LXC container's rootfs are on top of ZFS filesystem.
I start with a newer kernel.
